If Doc doesn't have it. Try Googleing the part no you might be surprise on what else you will find it on. I needed the diaphragm for the accelerator pump for a Kohler magnum. Kohler wanted a fortune for their little kit and I didn't need the kit just the diaphragm. I found Harley used it on one of their carburetors so I went to Harley they had in stock and it was only $15.
